Subnautica, the underwater adventure game made by Unknown Worlds (previously known for Natural Selection), can now be downloaded for free on PC via the Epic Games Store. As long as you do that before the end of December 27th (11:59 PM EST, to be exact), it’s yours to keep. This is part of Epic’s initiative to bolster visibility on the new Games Store; they have promised to give away one game every two weeks. The next one will be Super Meat Boy, available for free from December 28th.

If you haven’t had the chance to try it before, this is a great opportunity. In our review, Francesco had strong praise for the game.
